Abstract

The utility model discloses a front anti-collision beam assembly which comprises a front anti-collision beam body (1), a front anti-collision left installation plate (2) and a front anti-collision right installation plate (3). The front anti-collision left installation plate (2) and the front anti-collision right installation plate (3) are respectively located at the left end and the right end of the front anti-collision beam body (1), are in a split type structure, are connected together in a welding mode, and are both formed by cold stamping high-strength steel plates. The front anti-collision beam body (1) is provided with weight-reducing holes (4). The front anti-collision beam assembly can absorb more energy, greatly reduces possibility of occurrence of bending deformation in front face 40% deviated collision, and prevents a collision side from generating invasion amount beyond target value due to the fact that impact force can be transmitted from one side to the other side, thereby protecting passengers and a main body structure of a vehicle body.

Description

A kind of front anticollision beam assembly

Technical field

The utility model relates to a kind of front anticollision beam assembly.

Background technology

In the front anti-collision beam design, need to consider the requirement of pedestrian protecting, low speed collision laws and regulations requirement, head-on crash, offset collision and insurance association at the limited arrangement space Inner of automotive front end, seek an equilibrium point that reaches each requirement that energy is best.Also need consider simultaneously the requirements such as punching press, welding and replacing of this beam structure.

At present, the forming process of front anti-collision beam has cold stamping, heat stamping and shaping and roll-forming, their good and bad as shown in the table on expense, technique, stock utilization, performance, arrangement space:

	Cold stamping	Roll-in	Heat forming
				Die cost	More expensive	Relatively cheap	Expensive
Stock utilization	Generally	Relatively high	Generally
				Inheritance	Poor	Relatively better	Poor
Take arrangement space	The cross section is flexible, less	Deng radian, relatively large	The cross section is flexible, less
				Weight loss effect	Generally	Generally	Obviously

The utility model content

Technical problem to be solved in the utility model is to provide a kind of front anticollision beam assembly for problems of the prior art, its objective is and to absorb more impact energy in collision, avoid or reduce infringement to the front deck parts, reduce service expenditure, improve driver and crew's safety.

The technical solution of the utility model is the left adapter plate of front anti-collision beam, the right adapter plate of front anti-collision beam that this kind front anticollision beam assembly comprises the front anti-collision beam body and is positioned at the left and right two ends of front anti-collision beam body, and described front anti-collision beam body, the left adapter plate of front anti-collision beam, the right adapter plate of front anti-collision beam are split-type structural, and described front anti-collision beam body is provided with lightening hole.

The left adapter plate of described front anti-collision beam and the right adapter plate of front anti-collision beam are arranged on the left and right two ends of front anti-collision beam body by the mode of welding.

Described front anti-collision beam body, the left adapter plate of front anti-collision beam and the right adapter plate of front anti-collision beam all adopt the high tensile steel plate cold stamping to form, and the little 0.2mm of thickness of the Thickness Ratio front anti-collision beam body of the left adapter plate of front anti-collision beam and the right adapter plate of front anti-collision beam.

This kind front anticollision beam assembly with said structure has the following advantages:

1. this kind front anticollision beam assembly has higher strength and stiffness; except absorbing more multi-energy; the possibility that occurs bending and deformation in positive 40% offset collision reduces greatly; impulsive force can be delivered to opposite side from a side by front anti-collision beam; stop the intrusion amount that expected value occurs to surpass side of clashing into, thereby realize protection occupant and main structure of vehicle body function.

2. the right adapter plate of this kind front anticollision beam assembly front anti-collision beam body and front anti-collision beam, the right adapter plate of front anti-collision beam directly weld, realized the simplicity of welding process, wherein the right adapter plate of front anti-collision beam, the right adapter plate of front anti-collision beam are the convertibilitys that has guaranteed front anti-collision beam.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is blast structural representation of the present utility model.

In Fig. 1-2,1: the front anti-collision beam body; 2: the left adapter plate of front anti-collision beam; 3: the right adapter plate of front anti-collision beam; 4: lightening hole.

The specific embodiment

By structure shown in Fig. 1-2 as can be known, this kind front anticollision beam assembly comprises front anti-collision beam body 1 and is positioned at the left adapter plate 2 of front anti-collision beam at front anti-collision beam body 1 left and right two ends, the right adapter plate 3 of front anti-collision beam, and described front anti-collision beam body 1, the left adapter plate 2 of front anti-collision beam, the right adapter plate 3 of front anti-collision beam are split-type structural; The left adapter plate 2 of front anti-collision beam and the right adapter plate 3 of front anti-collision beam are arranged on the left and right two ends of front anti-collision beam body 1 by the mode of welding, then are fixed on body structure with nut by the via hole on collision prevention girders.The left adapter plate 2 of front anti-collision beam and the right adapter plate 3 of front anti-collision beam are arranged on the left and right two ends of front anti-collision beam body 1 by the mode of welding, realized the simplicity of welding process; Wherein front anti-collision beam left/right adapter plate is in order to guarantee the convertibility of front anti-collision beam.

Front anti-collision beam body 1 is provided with lightening hole 4, effectively reduces the gravity of front anticollision beam assembly, has satisfied the requirement of automotive light weight technology.

Front anti-collision beam body 1, the left adapter plate 2 of front anti-collision beam and the right adapter plate 3 of front anti-collision beam all adopt the high tensile steel plate cold stamping to form, and the little 0.2mm of thickness of the Thickness Ratio front anti-collision beam body 1 of the left adapter plate 2 of front anti-collision beam and the right adapter plate 3 of front anti-collision beam.

Front anticollision beam assembly structure of the present utility model can absorb more impact energy in collision, can avoid or reduce the infringement to the front deck parts, reduces service expenditure; In addition, this structure has higher strength and stiffness, and except absorbing more multi-energy, the possibility that occurs bending and deformation in positive 40% offset collision reduces greatly, impulsive force can be delivered to opposite side from a side by front anti-collision beam, stops the intrusion amount that expected value occurs to surpass side of clashing into.Thereby realize protection occupant and main structure of vehicle body function.

Punching press, the welding process of this front anti-collision beam structure are simple, can tackle reliably various collision requirements.Its structure not only will satisfy the laws and regulations requirement of high and low speed collision, and requires it when vehicle generation low speed collision, absorbs collision energy, guarantees that main structure of vehicle body is not damaged; When vehicle generation high-speed crash, utilize and self fully be out of shape the absorption collision energy, with the protection occupant safety.
